Filed: 1985-04-10
Abstract: PURPOSE:To provide a solenoid valve resistant to a contaminative fluid and a corrosive fluid and having a long life, by completely separating a solenoid section from a valve section by means of a diaphragm sheet. CONSTITUTION:When a pivot type armature core 4 is swung in one direction by excitation of a solenoid 1, an end 6 of the armature core 4 is swung in the other direction. As a result, a diaphragm sheet 16 is moved away from one valve seat 11, and is seated on the other valve seat 13 to close the valve. On the other hand, when the solenoid 1 is deexcited to swing the end 6 of the armature core 4 in one direction, the diaphragm sheet 16 is moved away from the valve seat 13, and is seated on the valve seat 11 to close the valve. In the course of selecting two-way or three-way selection mode, there is no possibility of the armature core 4 being contaminated or corroded since the diaphragm sheet 16 completely separate the solenoid section 1 from a valve section 2, and the end 6 of the pivot type armature core 4 is positioned on the side of the solenoid section 1.
